To be consistent with the phrasing of this particular document we saw earlier, you would have said "without basis", but I think the use of `basis` did not spread beyond "git bundle" documentation. If we were writing "git bundle" and its documentation from scratch using more modern lingo, we probably would say "negative revisions" here. Note that the word `refspec` has no place in the context of this sentence; they are to specify the mapping of refs between the repository in which transferred objects originate and the repository that accept the objects. Also note that `basis` discussed in 'git bundle' is a bit wider concept than `negative revisions`, so mere mechanical replacements would not be sufficient as a preliminary modernization/prepation step for this patch. > +If you want to match `git clone --mirror`, which would include your > +refs such as `refs/remotes/*`, use `--all`. > +If you want to provide the same set of refs that a clone directly > +from the source repository would get, use `--branches --tags` for > +the `<git-rev-list-args>`. This is not wrong per-se, but may lead to confusion. The readers must be able to learn: - "git clone --mirror full.bndl dst/" from a full bundle created with "git bundle create full.bndl --all" can mimic creation of a full mirror of the original. - "git clone full.bndl dst/" from such a bundle does *not* result in creation of a mirror. - "git clone slim.bndl dst/" from a minimum bundle created wth "git bundle create slim.bndl --branches --tags" would be sufficient to obtain the same result as the above. - "git clone --mirror slim.bndl dst/" from such a minimum bundle cannot mimic creation of a full mirror of the original. I am not sure the second point is conveyed well with the new paragraph. That is, "--all" must be used if the resulting bundle is meant to be usable to "--mirror" clone from, but it can still be used to clone normally. If you do not intend to mirror-clone from, there is not much point in using "--all" to record extra refs. Not having the new paragraph does not convey anything at all, so it definitely is an improvement, though ;-) Thanks.
